This is the severe threat for Friday and Friday night. Discussion below:-From northern Missouri south into AR storms will be ongoing in the morning. These will weaken by afternoon but debris clouds will linger long the cold front perhaps limiting the severe threat some. However a strong jet stream will be blasting along and just ahead of a strong cold front, and CAPE values will be around 1000 J/kg which is supportive of some thunderstorm development. I think the main threat on Friday will be a squall line along the cold front. Instability will be marginal but with the extra lift of the front storms will likely fire along it. Again a strong jet stream will be blowing not to far aloft which will enhance the damaging wind threat. But I do not think too much of the tornado threat because there will be a lot of clouds, especially from whats left of the morning storms. This will limit how unstable things can get and limit how many super cells will be able to develop ahead of the line. I will post an updated map and discussion tomorrow.
